SAFETY-GUARD FOR LOCKS AND LATGHES.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed July 2, 1909. Serial No. 505,640.

To all whom it may concem:

Be it known that I, GEORGE E. HOSCH, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Safety-Guard for Locks and Latches, of which the following is a full, clear, and exact description.

My invention relates 'to safety guards for locks an latches, my more particular purpose being to provide a guard having substantially the form of a plate provided with means whereby it may be fastened upon a door jamb, or the like, for the purpose of preventing the bolt of the lock or latch from being forced back, from the outside of the door. with the aid of a knife, screw-driver, or other instrument.

My invention further comprehends giving the guard such simple form and suitable shape that the guard may be quickly and easily secured in position without the necessity of cutting away any of the woodwork in the door frame and without the use of any screws or nails, and is noteasily removed.

Referenece is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a fragmentary horizontal section through a portion of a door and the jamb associated therewith, the door being provided with a lock and the jamb having my improved safety guard mounted upon it; Fig. 2 is a front elevation showing the jamb and stop bead with my improved safety guard mounted upon the jamb and resting against the stop bead; and Fig. 3 is a perspective showing the safety guard considered as an article of manufacture.

A door jamb is shown at 4 and a sto bead which is permanently connected with it appears at 5.

A door is shown at (3 and mounted upon it is a lock or latch 7 rovided with a bolt 8 which is adapted to e thrust into a keeper 9, the latter being mounted rigidly upon the jamb.

The parts just described may be of the usual or any desired construction.

The safety guard, which is shown completely in Fig. 3, comprises a plate 10 of metal having ears 11 integral with it and bent outwardly from it in a plane crossing from the tongue so as to leave an aperture 15. The heard 14 and the aperture 15 are each of substantially triangular form and in the finished article the beard 14L inclines a few degrees from the general plane of the tongue-13 and plate 10. The tongue 13 is provided with a sharp edge 16.

- The operation of my device is as follows: In order to mount the safety guard in position the sharp edge 16 is placed against the jamb 4 and the plate isdriven ed ewise toward the jamb, preferably by aid 0 awooden mallet or ordinary hammer. The tongue 13 being thus driven into the j amb, the ears 11 lodge against the inner face of the j amb and the curved edges 12 are sunken slightly into it so that the ears 11 present as a whole a slightly rounded appearance as indicated in Fig. 1. The parts are so apportioned that the distance from the ears 11 to the op posite edge of the plate 10 is e ual to the.

thickness of the stop head 5, as wil be understood from Fig. 1. By this arrangement the plate when driven in, as indicated in Fig. 1, is brought to such position that the ears 11 lodge against the inner face of the jamb at the same time that the outer edge of the plate 10 becomes flush with the outer face of the stop bead 5. I

I do not limit myself to the precise shape of the safety device shown in Fig. 3, as obviously the various proportions of the several parts of this. device may be varied within reasonable limits without departing from the spirit of my invention. Neither do I limit myself to any particular material out of which the safety device is constructed, though ordinarily I prefer to use stampings of sheet metal for the purpose.

The safety device being once in position, as indicated in Fig. 1, the beard 14 bites into the jamb so that the safety device can not be too readily extracted. 1

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A device of the character described, comprising a plate of sheet metal provided with a tongue and also provided with ears projecting in a direction lateral to the general direction of said tongue, said ears being slightly rounded and provided with sharp edges to be driven slightly into a soft material.

2. A device of the character described, comprising a plate of sheet material provided wit a tongue having a sharp edge, said plate being further )rovided with ears extending laterally from it, said tongue having a beard integral with it and inclining 10 slightly away from the general plane occupied by it for the purpose of preventing the too easy extraction of said tongue from a material into which it may be drlven.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribin witnesses.
